40 Series Ohmite 40 Series resistors are the most economical conformal silicone-ceramic coated resistors offered. These allwelded units are characterized by their low temperature coefficients and resistance to thermal shock, making them ideal for a wide range of electrical and electronic applications. Units with 1% and 5% tolerances are identical in construction and electrical specifications. Durable but economical 40 Series resistors exceed industry requirements for quality.
